The Mets have shut down Megill (elbow) from throwing after the 30-year-old right-hander experienced tightness in his right arm, Anthony DiComo of MLB.com reports.

Megill was knocked around for five runs on four hits and two walks while striking out three batters across two innings during Sunday's rehab start with Triple-A Syracuse. Laura Albanese of Newsday notes that Megill experienced tightness when throwing his secondary pitches and will undergo an MRI, but this latest setback puts a potential return this season in jeopardy.

Cabrera (elbow) resumed a throwing program Monday, Christina De Nicola of MLB.com reports.

Cabrera looked to be in danger of missing the rest of the season after he was placed on the injured list Sept. 1 due to a right elbow sprain, but his ability to resume throwing a week later leaves the door open for him to pitch again in 2025. Because he hasn't been shelved for a prolonged period, Cabrera should have sufficient time to get stretched back out for a starting role, provided he experiences no hiccups during the buildup process. Prior to being shut down last week, Cabrera had submitted a 3.50 ERA, 1.12 WHIP and 52:14 K:BB In 46.1 innings over his eight starts since the All-Star break.

The Marlins activated Junk (elbow) from the 15-day injured list Monday.

Junk will start Monday's game against the Nationals after missing a couple weeks with right ulnar nerve irritation in his pitching elbow. The right-hander threw 61 pitches in his lone rehab outing with Triple-A Jacksonville last Tuesday, so he will likely be facing a bit of a limited workload Monday.

Gore (shoulder) threw a 25-pitch bullpen session Saturday and will throw off the mound again Tuesday, Spencer Nusbaum of The Washington Post reports.

Gore has progressed well since landing on the 15-day injured list Aug. 30 due to left shoulder inflammation. It's unclear whether the Nationals will ask the left-hander to make a rehab start prior to being activated, but Gore is tracking toward rejoining the big-league rotation at some point later this month.

The Marlins will activate Weathers (lat) from the 60-day injured list to start Thursday's game against the Nationals in Miami, Christina De Nicola of MLB.com reports.

After completing rehab starts with Triple-A Jacksonville on Aug. 30 and this past Thursday, Weathers returned to Miami on Monday and tossed a live bullpen session, per Daniel Alvarez-Montes of ElExtraBase.com. With Weathers' lat checking out fine following the throwing session, the Marlins have cleared him to slot back into the rotation for the series finale with Washington. Because Weathers has been on the shelf since June 9 due to the left lat strain and built up to 68 pitches in his most recent rehab start, he'll likely have a light workload restriction in place Thursday. Prior to landing on the IL, Weathers had made five starts this season for Miami, going 1-1 with a 3.28 ERA, 1.05 WHIP and 23:8 K:BB in 24.2 innings.

Nikhazy (elbow) struck out three batters and allowed one hit and no walks over two scoreless innings Saturday for Triple-A Columbus after being reinstated from the 7-day injured list.

Nikhazy was on the shelf for just over a month due to a left elbow impingement. The left-hander didn't require a rehab assignment prior to rejoining the Columbus rotation, though he was eased back into action Saturday with a light workload.

The Brewers announced Wednesday that Henderson (elbow) has resumed playing catch out to 90 feet, MLB.com reports.

After being placed on the 15-day injured list Aug. 8 due to a right flexor tendon strain before being shifted to the 60-day IL a few weeks later, Henderson won't be eligible to return before the end of the regular season. However, the Brewers are leaving the door open for Henderson to be activated at some point during the postseason, though a return would be contingent on him avoiding any setbacks during the ramp-up process. Even if his throwing program proceeds smoothly, Henderson likely won't be able to get stretched out enough to handle a starting role in October, so the Brewers would presumably have him prepare for a multi-inning relief gig.

Megill (elbow) allowed five earned runs on four hits and two walks while striking out three in two innings during his rehab start Sunday with Triple-A Syracuse. He also hit two batters and threw a wild pitch.

After turning in a 21:6 K:BB and posting a 1.93 ERA over 14 innings in his first four rehab starts between Syracuse and Double-A Binghamton, Megill has regressed while making his last two minor-league appearances for the Triple-A club. Between those outings, Megill has allowed six earned runs on 10 hits and four walks across six innings. Though he's now tossed at least 65 pitches in each of his last four appearances in the minors and looks to be stretched out enough to handle a starting role, Megill's poor showings his last two times out have probably removed him from consideration for a spot in New York's rotation once he's activated from the 60-day injured list. The Mets look content to proceed with rookies Jonah Tong and Brandon Sproat at the back end of the rotation, so Megill could be ticketed for a long-relief role with the big club once his rehab assignment ends.

Harrison (ankle) made a one-inning start for Triple-A Worcester in the first game of a doubleheader Sunday, striking out two batters while allowing one earned run on two hits and one walk.

Harrison appeared to be a candidate to make a start or bulk-relief appearance with the Red Sox last week, but he sustained a minor ankle injury that may have played a part in him being bypassed for a promotion. The southpaw made enough progress in his recovery from the injury to pitch Sunday for Worcester, though he took on a much more limited workload than he typically handles during his starts.

King is expected to be activated from the 15-day injured list to start Tuesday's game against the Reds at Petco Park, Kevin Acee of The San Diego Union-Tribune reports.

He would also be lined up for a second start this week Sunday at home versus the Rockies. King has made only one start for the Padres since late May, having missed most of that time due to a shoulder issue and more recently a knee injury. The Padres are aiming for him to make four starts before the end of this month as he gets ramped up for the postseason. King made an unofficial five-inning start at the Padres' spring training complex in Arizona this past Thursday, so he could be capable of covering at least five frames versus the Reds.
